Stay calm and collect facts

During a security alert, avoid random changes. Collect the device name, user, time, alert message, source, destination, and observed behavior.

Identify the scope

Determine whether the alert affects one device, one user, multiple systems, cloud accounts, email, or network-wide resources.

Contain safely

Containment may include disconnecting a device from the network, disabling a compromised account, blocking an indicator, or isolating email messages. Follow your organization’s policy.

Document everything

Good notes help investigation, compliance, insurance, management communication, and future prevention.

Escalate when needed

Escalate serious incidents quickly, especially suspected ransomware, data theft, admin account compromise, or active attacker activity.

Check sign-in logs
Isolate affected endpoint
Export relevant logs
